X/3 = 8/12
12 * x = 8 * 3
12x = 24
x = 2
8/12 = 4/y
8y = 48
y = 6
Answer:
12
Step-by-step explanation:
if you multiply everything by 5, then you can get rid of the fraction and the equation would now look like this:
x - 40 = 20
and now you can answer this simply
x - 40 = 20
+40 +40
x = 60
and since you multiplied 5 beforehand, now you have to divide by 5 to get the real answer
60 ÷ 5 = 12
therefore, x = 12
If the amount of monkeys is m, lions is a, and lizards is b, then a+b+m=151, 17+a=m (since there are 17 more monkeys than lions), and 30+a=b. Substituting those values in (17+a=m and 30+a=b), we have 30+17+a+a+a=151=47+3a. Subtracting 47 from both sides, we get 104=3a. Next, we can divide both sides by 3 to get 104/3=a (the number of lions), 104/3+17=the number of monkeys, and 104/3+30=the number of lizards. Somehow we end up with a fraction (not a whole number), so there are 2/3rds of monkeys floating around using this logic.
